2011-05-12Removed mv_bits_sadcostScott LaVarnway
This sad cost is being generated but never used. Change-Id: I562eebdcb792b743770954feca365b5b37491ecd
2011-05-12Using int_mv instead of MVScott LaVarnway
The compiler produces better assembly when using int_mv for assignments. The compiler shifts and ors the two 16bit values when assigning MV. Change-Id: I52ce4bc2bfbfaf3f1151204b2f21e1e0654f960f

2011-05-10remove a variable no longer in useYaowu Xu
The variable is introduced in commit 2e53e9e53 to make more use of trellis quantization, but this is no longer necessary after RDMULT was made adaptive in a number of later commits. Change-Id: I7420522ec7723f38cf77033466c25afb405d52ae

global values were being referenced, but the GOT was not being set up. as the GOT is only required for PIC, this issue wasn't caught in the default configuration. Change-Id: I8006e53776139362a76f2c80cf9d0f8458602b2f http://code.google.com/p/webm/issues/detail?id=328
2011-05-10Merge "Use diamond search to replace full search in full-pixel refining search"Yunqing Wang
2011-05-09Use diamond search to replace full search in full-pixel refining searchYunqing Wang
In NEWMV mode, currently, full search is used as the refining search after n-step search. By replacing it with an iterative diamond search of radius 1 largely reduced the computation complexity, but still maintained the same encoding quality since the refining search is done for every macroblock instead of only a small precentage of macroblocks while using full search. Tests on the test set showed a 3.4% encoding speed increase with none psnr & ssim loss. Change-Id: Ife907d7eb9544d15c34f17dc6e4cfd97cb743d41

2011-05-06fix a bug related to gf_active_flags in multi-threaded encoderYaowu Xu
Paul pointed out that the pointer to the gf_active_flags is not being properly incremented in multithreaded encoder. This commit fixes the issue by making sure the gf_active_ptr points to the starting of next group of mb rows. Change-Id: I3246e657d23beabb614dfb880733a68a5fd7e34c

2011-05-06Don't override active_worst_quality in 2 passJohn Koleszar
Commit db5057c introduced a bug in that the active_worst_quality selected by the 2 pass rate controller was being overridden for key frames, causing a severe quality loss. Change-Id: I4865a6fbe3e94e9b4fb9271c7dd68b455d7b371d

2011-05-06Fix semaphore emulation on WindowsAron Rosenberg
The existing emulation of posix semaphores on Windows uses SetEvent() and WaitForSingleObject(), which implements a binary semaphore, not a counting semaphore as implemented by posix. This causes deadlock when used with the expected posix semantics. Instead, this patch uses the CreateSemaphore() and ReleaseSemaphore() calls (introduced in Windows 2000) which have the expected behavior. This patch also reverts commit eb16f00, which split a semaphore that was being used with counting semantics into two binary semaphores. That commit is unnecessary with corrected emulation.

This patch is to fix a rare hang in multi-thread encoder that was only seen on Windows. Thanks for John's help in debugging the problem. More test is needed. Change-Id: Idb11c6d344c2082362a032b34c5a602a1eea62fc

2011-05-03Modify HEX searchYunqing Wang
Changed 8-neighbor searching to 4-neighour searching, and continued searching until the center point is the best match. Test on test set showed 1.3% encoding speed improvement as well as 0.1% PSNR and SSIM improvement at speed=-5 (rt mode). Will continue to improve it.

Insertion sort performs better for sorting small arrays. In real- time encoding (speed=-5), test on test set showed 1.7% performance gain with 0% PSNR change in average. Change-Id: Ie02eaa6fed662866a937299194c590d41b25bc3d

2011-04-27Speed up VP8DX_BOOL_DECODER_FILLJohn Koleszar
The end-of-buffer check is hoisted out of the inner loop. Gives about 0.5% improvement on x86_64. Change-Id: I8e3ed08af7d33468c5c749af36c2dfa19677f971
2011-04-27Update VP8DX_BOOL_DECODER_FILL to better detect EOSJohn Koleszar
Allow more reliable detection of truncated bitstreams by being more precise with the count of "virtual" bits in the value buffer. Specifically, the VP8_LOTS_OF_BITS value is accumulated into count, rather than being assigned, which was losing the prior value, increasing the required tolerance when testing for the error condition.

2011-04-26Move pick_frame_size() to ratectrl.cJohn Koleszar
This is a first step in cleaning up the redundancies between vp8_calc_{auto_,}iframe_target_size. The pick_frame_size() function is moved to ratectrl.c, and made to be the primary interface. This means that the various calc_*_target_size functions can be made private. Change-Id: I66a9a62a5f9c23c818015e03f92f3757bf3bb5c8
